### Build project
cmake --build . --target all

### Deploy files
scp librpi-vk-driver.so [user]@[ipaddress]:/home/[user]/librpi-vk-driver.so
scp rpi-vk-driver.json [user]@[ipaddress]:/home/[user]/rpi-vk-driver.json
scp install.sh [user]@[ipaddress]:/home/[user]/install.sh

### Run install.sh on your RPi
